MILWAUKEE, \VISCONSIN, ASSIGNOR T MOE- SHADE HOLDER Application filedAugust 24, 1927. Serial No.

This invention relates to shade holders and has for its object toprovide a shade holder with shade clamping means that will positivelylock the shade against removal without danger of injury thereto andwithout impairing the ornamental appearance of the shade holder.

Another object of the invention is to provide such a clamping mechanismfor shade holders that will be simple in its construction andinexpensive to manufacture without involving material change of theshade holder shell.

Another object of the invention is to provide a shade holder with a lampsocket attaching means that will be simple in its construction and thatwill be firmly and rigidly held in place against independent movement.

lVith the above and other objects in view the invention consists in theshade holder, its parts and combinations of parts as herein claimed andall equivalents.

Referring to the accompanyingdrawings in which like characters ofreference indicate the same parts in different views,

Fig. 1 is a central sectional view of a shade holder constructed inaccordance with this invention Fig. 2 is a bottom view thereof with theshade and lamp removed;

Fig. 3 is a detail sectional view on line 33 of Fig. 1 showing themanner of securing the lamp socket yoke against turning;

Fig. 1 is a sectional detail view of one of the shade clamps; and

Fig. 5 is a perspective view of the locking lever and its washer.

In these drawings 10 indicates the shell member of usual ornamentalshape having a supporting ring 11 passed through the center with a nut12 threaded thereon, as usual. An arch-shaped yoke member 13 curved tofit the curvature of the top of the shell member is mounted therein byhaving a central opening fitting over the threaded tubular stem of thering member and is clamped in place by the nut 12. The shell member hasslits cut in it in line with the edges of the yoke member 13 and themetal at the sides of the slits is pressed inwardly to form projectinglugs 14 engaging the edges of the yoke member to prevent it fromturning, as best seen in Fig. 3. This enables the lamp 15 to be threadedin and out of its socket 16, which is secured between the ends of theyoke member, without the turning of the yoke in the shell member.

The clamps for the flaring neck of the shade 17 consist of springtongues 18 attached to the shell member 10 by single rivets 19 withtheir upper ends bent to engage the shoulder 20 ot. the shell member toprevent the tongues from swinging on the rivets, said tongue membershaving their lower ends bent upwardly to form yielding engaging meansfor engaging the neck of the shade. The tongue members are movedinwardly and held in thelr clamping engagements by angular lockinglevers 21 passed throughopenings near. the edge of the shell member andcapable of swinging from a closed position as shown at the left in Fig.1 to an open position, as shown at the right in Fig. 1.

The locking lever is formed of a narrow stem portion which is bent togive it the angular shape and an enlarged head or cam portion 22preferably rectangular in shape for engaging the spring tongue 18, andto avoid wear of the bearing shoulders of the enlarged head 22 on thethin shell member 10, asteel washer 23 is loosely mounted on the stem sothat the shoulders bear on it.

When the lever is in its open position the head 22 is upright and thespring tongue 18 is released permitting the flaring edge of the shadeneck to freely pass for entering the shade in the holder or for removingit therefrom, but when the lever is swung upwardly to'its closedposition the head acts as a cam pressing the lower end of the tonguemember inwardly for tightly locking the shade against removal andyieldingly holding it against independent movement.

The pressure of the spring tongue against the locking lever is incapableof urging it to its open position, since the head 22 thereof passes itsdead center position before reaching the locked position and the stemportion bears directly against the shell. When so locked in place theshade cannot be removed and the narrow lever stems are unnoticeable asthey bear against the shell but they are easily manipulated forreleasing or looking the shade.

To facilitate the entry of the flaring neck of the shade between thespring tongues 18 and prevent it from passing between the spring tonguesand the shell, each spring tongue has a projection 24 cut therefrom andextending outwardly from its bent lower end to enga e the shell beneaththe loose washer.

The shade holder of this invention is simple in its construction andinexpensive to manufacture, provides for fixing the lamp socket againstrotation and for mounting the shade clamps without material alterationof the shell member, and affords a shade clamp construction that isstrong and durable and highly eflicient for preventing the withdrawal ofthe shade even when force is exerted thereon. It is neat and ornamentalin its appearance and positive in its action, with no screw threads tobecome stripped, no soldered parts to become loose and no frailconnections to wear.

What I claim as new and desire to secure by Letters Patent is:

1. A shade holder, comprising a shell provided with a shoulder, springtongues riveted to the shell and having bent ends engaging the shoulderand having their other ends bent to form yielding shade engagingportions, angular locking levers with stems extending through openingsin the shell member and with enlarged heads forming shoulders, washerson the stems between the shoulders and the shell member, said headsengaging the spring tongues to force them inwardly, and lugs bent outfrom the spring tongues to engage the shell member and block the spacebetween the spring tongues and the shell member.

2. A shade holder, comprising a shell member, spring tongues securedthereto, angular locking levers extending through openings in the shellmember and having shoulders bearing inside the shell member, saidlocking levers engaging the spring tongues for moving them inwardly, andlugs on the spring tongues engaging the shell member for blocking thespace between the spring tongues and the shell member.

In testimony whereof I affix my signature.

ALEXANDER K. SUTHE RLAND.
